Health-Related Quality of Life Issues Experienced by Thoracic and Breast Sarcoma Patients: A Rare and Understudied Group

2021

Thoracic and breast sarcomas constitute a rare subgroup within the sarcoma population. There is limited knowledge about their health-related quality of life (HRQoL) and a valid disease-specific HRQoL instrument is lacking. This qualitative study aimed to investigate the HRQoL issues experienced by a small group of thoracic and breast sarcoma patients. Semi-structured interviews with 19 thoracic and four breast sarcoma patients were conducted and thematically analysed. Physical issues mentioned by both groups were fatigue, sleep disturbances, pain, wound infections, and symptoms related to chemotherapy and radiotherapy. Tightness in the back and restrictions in performing tasks above arm hei…

Methods for evaluating causality in observational studies.

2019

BACKGROUND: In clinical medical research, causality is demonstrated by randomized controlled trials (RCTs). Often, however, an RCT cannot be conducted for ethical reasons, and sometimes for practical reasons as well. In such cases, knowledge can be derived from an observational study instead. In this article, we present two methods that have not been widely used in medical research to date. METHODS: The methods of assessing causal inferences in observational studies are described on the basis of publications retrieved by a selective literature search. RESULTS: Two relatively new approaches—regression-discontinuity methods and interrupted time series—can be used to demonstrate a causal relat…

The Impact of Age on Quality of Life in Breast Cancer Patients Receiving Adjuvant Chemotherapy: A Comparative Analysis From the Prospective Multicent…

2016

Elderly breast cancer patients are affected by poorer quality of life (QoL) compared to younger patients. Because QoL has a relevant impact on guideline-adherent treatment, elderly breast cancer patients are often undertreated, especially with regard to adjuvant chemotherapy, and overall survival is decreased. Thus, understanding the impact of chemotherapy on QoL in elderly patients is crucial. This study compared QoL in patients aged 65 years and 65 to 70 years receiving adjuvant chemotherapy as a secondary outcome in the prospective randomized multicenter ADEBAR trial.Patients with lymph node-positive breast cancer were prospectively randomized for either sequential anthracycline-taxane o…

Quality of Life in NSCLC Survivors - A Multicenter Cross-Sectional Study.

2019

The objective was to assess quality of life (QoL) in lung cancer survivors, compare it to the general population, and identify factors associated with global QoL, physical functioning, emotional functioning, fatigue, pain, and dyspnea.Data from NSCLC patients who had survived 1 year or longer after diagnosis were collected cross-sectionally in a multicenter study. QoL was assessed with the European Organisation for the Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-C30 and the lung cancer module QLQ-LC13 across different clinical subgroups and compared to age- and sex-standardized general population reference values. Multivariable linear regression analyses wer…

2016

Abstract Background The recommendation for adjuvant dose-dense chemotherapy in high risk primary breast cancer is heterogeneous among guidelines. Understanding the impact on QoL is thereby a crucial factor, especially if the benefit is potentially low. This study aims to assess QoL as a secondary outcome in the prospective randomized multi-center ADEBAR trial. Methods QoL was assessed at baseline (t1), before cycle 4 FEC and cycle 5 EC-DOC (t2), 4 weeks after chemotherapy (t3) and 6 weeks after radiation (t4) using the European Organization for Research and Treatment for Cancer (EORTC) Quality of Life Core Questionnaire (QLQ-C30) and the Breast Cancer-Specific Module (QLQ-BR23). Results 130…

2020

Hematologic toxicities are one of the greatest challenges in adjuvant chemotherapy for breast cancer. This analysis of the ADEBAR trial aims to evaluate application and effect of granulocyte colony-stimulating factor (G-CSF) and epoetin alfa (EPO) on hematologic parameters and fatigue in patients with breast cancer during chemotherapy.In the ADEBAR trial, 1493 patients with node-positive primary breast cancer were randomized to either 6 × 5-fluorouracil, epirubicin, and cyclophosphamide (FEC120) or 4 × epirubicin and cyclophosphamide followed by 4 × docetaxel (EC-DOC). Co-medication with G-CSF or EPO was applied to treat chemotherapy-induced leukopenia or anemia. Fatigue was assessed at bas…

Tobacco and alcohol consumption after total laryngectomy and survival: A German multicenter prospective cohort study

2016

Background We examined the relation of tobacco and alcohol consumption after total laryngectomy with overall survival (OS). Methods Tobacco and alcohol consumption was assessed at 5 time points after total laryngectomy. Patients were followed up for survival until December 31, 2014. A multivariate Cox regression was fitted to test for differences in OS. Results Three hundred fifty-nine patients were included in this study. Compared to former smokers, never smokers had hazard ratios (HRs) of 0.88 (95% confidence intervals [CIs] = 0.50–1.59), and continuous smokers 1.31 (95% CI = 0.87–1.96). Constantly high alcohol consumption after total laryngectomy had an HR of 2.19 (95% CI = 1.30–3.67). D…

Telephone Consultation

2016

The article by Martina Albrecht and her co-authors (1) addresses an important aspect of patient-oriented medical decision making in Germany: to what extent does the advice dispensed by the freely accessible telephone consultation services correspond with the evidence? In other words: Can people who turn to these services understand and trust the information they are given? Only six of 293 consultations fulfilled the criteria defined by the authors—on the face of it, an alarming outcome.

Relative and absolute socioeconomic inequality in smoking: time trends in Germany from 1995 to 2013

2020

Abstract Purpose This study aimed to investigate time trends in relative and absolute socioeconomic inequality in smoking prevalence in Germany using several indicators for socioeconomic position. Methods We conducted a repeated cross-sectional study using representative samples of the German population aged between 25 and 64 years in 1995, 1999, 2005, 2009, and 2013 (n = 857,264). Socioeconomic position was measured by indicators for income, education, and occupation. Relative and absolute socioeconomic inequalities were estimated with the regression-based relative index of inequality and the slope index of inequality, respectively. Trends in inequalities were estimated with interaction te…
